Transmission plates are rotatably arranged in the side walls at both ends of the shell 1, and the spiral blades 2 are arranged in front of the two transmission plates. The first driving member is a structure that provides a rotating force such as a motor, which drives the spiral blades 2 to rotate through the transmission plate, and then injects the sludge into the shell 1. The sludge can be transported by the rotating spiral blades 2. This is a prior art and will not be repeated here. One of the core innovations of the present utility model is that the feed pipe 3 is cylindrical, which is arranged below the shell 1 and is connected to the internal space of the shell 1. A clearing mechanism is arranged on the feed pipe 3. The clearing mechanism is a structure such as a scraper, and the scraper is in contact with the inner wall of the feed pipe 3. The purpose of such a setting is that when the sludge is transported, the clearing mechanism is started, so that the scraper slides vertically, so that the sludge attached to the inner wall of the feed pipe 3 can be scraped off to achieve the clearing effect.

[0030] As another embodiment of the utility model, the blockage clearing mechanism includes a scraper 4, which is rotatably arranged on the inner wall of the feed pipe 3; it also includes a second driving member for driving the scraper 4 to rotate. Specifically, the scraper 4 is arranged vertically and is set to an arc shape that matches the inner wall of the feed pipe. The second driving member is a structure that provides a rotating force such as a motor. The power is provided by the second driving member, so that the scraper 4 rotates along the inner wall of the feed pipe, thereby scraping off the sludge attached to the inner wall of the feed pipe.

[0031] Preferably, the scraper 4 is provided with an inclined surface 5 , which is vertically constructed at both ends of the scraper 4 and is located on the cleaning surface of the scraper 4 , so as to improve the scraping ability of the scraper 4 .

[0032] As another embodiment of the present utility model, the second driving member includes a ring gear 6, which is rotatably arranged on the discharge tube 3, a circular ring 7 is arranged on the ring gear 6, and the scraper 4 is fixedly connected to the circular ring 7.

Specifically, an annular groove is opened on the outer wall of the discharge tube 3, a connecting portion matching the annular groove is arranged on the ring gear 6, the circular ring 7 is arranged on the inner wall of the ring gear 6, the scraper 4 is fixedly connected to the upper surface of the circular ring 7, and the transmission shaft 9 It is arranged vertically, and the fixing part can be a matching structure of a bolt and a collar. The transmission shaft 9 is rotatably arranged in the collar, and the transmission gear 10 is arranged at the bottom end of the transmission shaft 9. The bevel gear set 8 includes two bevel gears meshing with each other, one of which is arranged vertically and the other is arranged horizontally, and both bevel gears are provided with connecting ends, one of which is fixedly connected to the transmission plate on the spiral blade 2, and the other is connected to the transmission shaft 9. The purpose of such arrangement is that the bevel gear set 8 can convert the vertical rotation of the spiral blade 2 into horizontal rotation. When the first driving member drives the spiral blade 2 to rotate, the transmission shaft 9 and the transmission gear 10 are driven to rotate through the bevel gear set 8. Since the transmission gear 10 is meshed with the ring gear 6, the ring 7 and the scraper 4 can be driven to rotate passively, so that the scraper 4 slides along the inner wall of the discharge pipe 3 to realize the passive clearing of the scraper 4.

[0033] Preferably, a plurality of scrapers 4 are provided, and the plurality of scrapers 4 are evenly arranged above the circular ring 7 . The plurality of scrapers 4 move simultaneously, which can increase the frequency of clearing blockages in the discharge pipe 3 .

[0034] Preferably, the fixing member includes a support rod 11, one end of the support rod 11 is fixedly connected to the discharge tube 3, and the other end of the support rod 11 is fixedly connected to a limiting ring 12, and the limiting ring 12 is rotatably connected to the transmission shaft 9.

As for a single sliding portion 14, two springs 15 are provided, and the two springs 15 are symmetrically arranged on both sides of the sliding portion 14. The purpose of such a setting is to control the rotation of the gear ring 6 when scraping the soft sludge inside the discharge pipe 3. At this time, the soft sludge When the blocking force of the sludge on the spring 15 is not enough to cause the spring 15 to deform, the elastic force of the spring 15 can drive the ring 7 and the scraper 4 to rotate. When the scraper 4 just contacts the hard dry sludge, the elastic force generated by the initial deformation of the spring 15 is small, which will make the scraper 4 unable to scrape off the sludge, and make the ring 7 and the gear ring 6 rotate relative to each other. When the two rotate relative to each other, the springs 15 on both sides of the sliding connection 14 will accumulate force. When the elastic force of the spring 15 is greater than the blocking force of the dry sludge, the elastic force of the spring 15 is instantly released, so that the dry sludge can be scraped off, and the scraper 4 repeatedly shakes under the action of the elastic force of the spring 15 and finally automatically resets, thereby achieving passive vibration of the scraper 4 while scraping off the sludge, so that the sludge on the scraper 4 can be shaken off.

[0036] Preferably, the spiral blade 2 is a shaftless spiral blade 2, that is, the interior of the spiral blade 2 is a hollow structure. The shaftless spiral blade 2 can reduce the adhesion area of ​​sludge during sludge transportation, thereby reducing sludge residue.
